Chapter 43 SSL Application

ZyWALL USG 50 User’s Guide

Use SSL VPN to allow remote users to manage LAN computers. Depending on the 
functions supported by the remote desktop software, they can install or remove 
software, run programs, change settings, and open, copy, create, and delete files. 
This is useful for troubleshooting, support, administration, and remote access to 
files and programs. 

The LAN computer to be managed must have VNC (Virtual Network Computing) or 
RDP (Remote Desktop Protocol) server software installed. The remote user’s 
computer does not use VNC or RDP client software. The ZyWALL works with the 
following remote desktop connection software:

• Windows Remote Desktop (supported in Internet Explorer)

• RealVNC
• TightVNC
• UltraVNC

For example, user A uses an SSL VPN connection to log into the ZyWALL. Then he 
manages LAN computer B which has RealVNC server software installed.

You can configure weblink SSL applications to allow remote users to access web 
sites. 

This example shows you how to create a web-based application for an internal 
web site. The address of the web site is http://info with web page encryption.
